摘　　要：目的调查我国北方某大型煤矿暴露于手传振动的掘进工人的症状与体征,以了解手传振动对作业人员健康的危害情况。方法采用问卷调查与体检相结合的方法对167名掘进工人进行调查,同时测量现场工人所用风锤的手传振动强度,应用SPSS 16.0软件进行统计分析。结果手传振动对作业人员的健康损伤以手麻、手部多汗、耳鸣、记忆力减退等症状为主,体检体征以凉温觉、痛觉、触觉、振动觉异常为主。对手麻这一典型症状进行危险因素分析,发现工龄、是否饮酒、每天接触手传振动的时间、是否佩戴手套均为影响因素。结论长期接触手传振动会导致作业人员健康损害,为有效预防手传振动对作业工人的健康危害,建议接触手传振动的作业人员要加强防护,降低振动强度暴露,减小工人发生危害的风险。Objective To investigate the symptoms and signs of heading drivers using hand-transmitted vibrating tools in a northern China coal mine in order to know the impact of hand-transmitted vibration on heading drivers.Methods 167 heading drivers were evaluated by questionnaire investigation and health test.The vibration strength of hand-transmitted vibrating tools was tested.SPSS 16.0 was used to analyze data.Results The main symptoms of workers using hand-transmitted vibrating tools were hand numbness,palmar hyperhidrosis,tinnitus and memory loss.The main sings were paresthesia of temperature,pain,touch and vibration sense.Analysis on risk factors of hand numbness shows that seniority showed that working years,drinking,duration of daily exposure to hand-transmitted vibration and gloves were affecting factors.Conclusions Occupational exposure to hand-transmitted vibration does harm to health.Protection and lowering intensity should be strengthened to protect workers using hand-transmitted vibrating tools.
